- Steel fibers are preferably used as metal fibers.
- the carbon or metal fibers are used in the organic sheet component in order to achieve the necessary for the battery technology electromagnetic shielding effect.
- the carbon or metal fibers are thereby added in a proportion just necessary to achieve the desired EM shielding property. With conventional organo sheets on pure glass fiber basis, no such effect could be achieved.
- Haibzeug / Organoblech is fully impregnated with this thermoplastic and consolidated, ie the fibers are already completely wetted with plastic, it is located no air in the material and the semi-finished product is converted into three-dimensional components only by heating and subsequent pressing in short cycle times.

Particularly preferably, the thermoplastics mentioned above in the organo-sheet component are also used here. In a very particularly preferred embodiment, both the organic sheet component and the plastic component b) are made of the same thermoplastic material.

Therefore, such geometrically complex or filigree areas are formed by the functional material, preferably a thermoplastic, with high electrical conductivity. With such a material are given by his processing behavior, preferably in injection molding, larger design freedom.
- the electrical conductivity of the plastic to be used as component b), preferably of the thermoplastic, is achieved according to the invention by addition of carbon, metal fibers or carbon nanotubes.
- carbon fibers, metal fibers or carbon nanotubes in the range from 0.1 to 30% by volume are added, the total filler content being in the range of 0.1 to 50 vol .-% based on 100% plastic component is.

- Plastic components can be welded on and the battery housing thus further functions are closely connected to this or the function of the battery.
